Explore the Effect and Target of Liraglutide on Islet Function in Type 2 Diabetic Rats by miRNA Omics Technology.
Article in Diabetes, metabolic syndrome and obesity : targets and therapy, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo analyze the effect and potential therapeutic targets of liraglutide in type 2 diabetes through miRNA expression profiling.
methodsTen of 30 SPF Wistar rats, males at 4 weeks old, were randomly selected as the control group and given conventional feed, the other rats adopted high-sugar and high-fat diet combined with an intraperitoneal injection of streptozotocin to establish a T2DM model. One unsuccessful rat was excluded, and the remaining rats were randomized to the model and the liraglutide group. Liraglutide group was subcutaneously injected with liraglutide 0.11 mg/kg for 8 weeks. The biochemical indicators and staining HE were detected. The expression of miRNA in pancreatic tissue was detected by miRNA sequencing. The intersection of miRNA difference was used to predict the target gene, then functional enrichment was performed to identify its possible biological functions and signal transduction paths. Finally, qRT-PCR was used to verify the results.
resultsCompared to the model group, the level of fasting blood glucose (FBG), glucagon and insulin resistance index (HOMA-IR) in the liraglutide group were significantly decreased, fasting insulin (FINS) and insulin sensitivity index (ISI) were increased. Nine differential miRNAs (miR-135a-5p, miR-144-5p, miR-21-3p, miR-215, miR-451-5p, miR-486, miR-122-5p, miR-181d-5p and miR-345-5p) were identified at the intersection through two miRNA sequencing. A total of 3359 related target gene predictions were obtained. GO and pathway analyses demonstrated that differentially expressed genes were closely related to cell proliferation, angiogenesis, and proteolysis. Significant signaling pathways included PI signaling system, autophagy, FoxO and HIF-1 signaling pathway.
conclusionLiraglutide could improve islet function by regulating nine miRNAs, and the related signaling pathways included PI signaling system, autophagy, FoxO and HIF-1 signaling pathway. Our study provided the basis and direction for further exploring the molecular mechanism of liraglutide on T2DM.
